Try:
convert -density 200 -trim -quality 100 -sharpen 0x1.0 $$i $$o
you can try different numbers for 200

Please bottom-post. Start your reply here:
So, with a great deal of help from Baris Erkus and according to his
instructions in https://github.com/ituast/itutezLyX ('Some adjustments
to LyX PDF previewer' part) I was able so solve the problem. To quote,
this works:
* Make sure the convert utility of ImageMagick is installed and made
available to path.
* Start LyX
* Go to "Preferences" under the "Tools" menu.
* Go to "Converters" under the "File Handling" section.
* Select "PDF(graphics)" from "From Format:" and "PNG" from "To Format:"
* To "Converter:" write : |convert -density *** -trim -quality 100
-sharpen 0x1.0 $$i $$o|, where *** can be 200 to start with. You may
try other values based on the results.
* Click "Add" button.
* Click "Apply" button.
* Click "Save" button.
Reconfiguring and restarting doesn't seem to be necessary, but won't hurt.
These instructions worked for Windows 7 using a new ImageMagick command
'magick' instead of 'convert' and with simple options:
|magick -density 200 $$i $$o|
|For some reason '-trim' option didn't work, but it's not mandatory.|
|In my ||Ubuntu 18.04.2, XFCE 4.12 setup all of these still didn't work
until I deleted default ||"PDF(graphics)->EPS" converter. With it LyX
converts all PDF pictures to EPS and then somehow internally converts
them to bad quality PNGs not using |||'EPS->PNG' converter settings
which exists by default.| Adding 'PDF->EPS' converter back breaks PDF
previews again. Even though 'EPS->PNG' converter exists, has correct
options (with density and everything) and flawlessly works from the
command line.

|So, delete |||"PDF(graphics)->EPS" converter if instructions for
|"PDF(graphics)->PNG" converter alone don't work.

JMarc Thanks, Helge and JMarc. I compiled the Lyx2.3.2 again, because in .lyx all the directories at the begin are empty. However, in the new compiled lyx it is the same. Am I to stupid? Can I get the files for these empty dirs from somewhere else? I meant 2.3.3, which is not released yet. If you can compile LyX, you can get the latest stable version with git clone git://git.lyx.org/lyx cd lyx git checkout 2.3.x ./autogen.sh ./configure make HTH, JMarc Thanks, JMarc, i do not know what I have to do here: wolfgang@wolfgang-Mr-Whisper-Ultra-SSD-II:/mnt/sdb/we$ mkdir lyx wolfgang@wolfgang-Mr-Whisper-Ultra-SSD-II:/mnt/sdb/we$ cd lyx wolfgang@wolfgang-Mr-Whisper-Ultra-SSD-II:/mnt/sdb/we/lyx$ ls wolfgang@wolfgang-Mr-Whisper-Ultra-SSD-II:/mnt/sdb/we/lyx$ git checkout 2.3.x fatal: Not a git repository (or any parent up to mount point /mnt/sdb) Stopping at filesystem boundary (GIT_DISCOVERY_ACROSS_FILESYSTEM not set). Wolfgang Sorry, JMarc, I see there is a Lyx Howto for git. Will try tomorrow. Thanks Wolfgang Thanks to all of you who helped. Installing lyx 2.3.3 shows now the English help files. Glad it worked.
